GetRole 搭配 a AWS SDK 或 CLI 使用

    /// <summary>
    /// Get information about an IAM role.
    /// </summary>
    /// <param name="roleName">The name of the IAM role to retrieve information
    /// for.</param>
    /// <returns>The IAM role that was retrieved.</returns>
    public async Task<Role> GetRoleAsync(string roleName)
    {
        var response = await _IAMService.GetRoleAsync(new GetRoleRequest
        {
            RoleName = roleName,
        });

        return response.Role;
    }

取得 IAM 角色的相關資訊

下列 get-role 命令會取得名為 Test-Role 之角色的相關資訊。

aws iam get-role \
    --role-name Test-Role

輸出：

{
    "Role": {
        "Description": "Test Role",
        "AssumeRolePolicyDocument":"<URL-encoded-JSON>",
        "MaxSessionDuration": 3600,
        "RoleId": "AROA1234567890EXAMPLE",
        "CreateDate": "2019-11-13T16:45:56Z",
        "RoleName": "Test-Role",
        "Path": "/",
        "RoleLastUsed": {
            "Region": "us-east-1",
            "LastUsedDate": "2019-11-13T17:14:00Z"
        },
        "Arn": "arn:aws:iam::123456789012:role/Test-Role"
    }
}

該命令會顯示連接至角色的信任政策。若要列出連接至角色的許可政策，請使用 list-role-policies 命令。

如需詳細資訊，請參閱 IAM 使用者指南中的建立 Word 角色。 AWS IAM

import (
	"context"
	"encoding/json"
	"log"

	"github.com/aws/aws-sdk-go-v2/aws"
	"github.com/aws/aws-sdk-go-v2/service/iam"
	"github.com/aws/aws-sdk-go-v2/service/iam/types"
)

// RoleWrapper encapsulates AWS Identity and Access Management (IAM) role actions
// used in the examples.
// It contains an IAM service client that is used to perform role actions.
type RoleWrapper struct {
	IamClient *iam.Client
}



// GetRole gets data about a role.
func (wrapper RoleWrapper) GetRole(ctx context.Context, roleName string) (*types.Role, error) {
	var role *types.Role
	result, err := wrapper.IamClient.GetRole(ctx,
		&iam.GetRoleInput{RoleName: aws.String(roleName)})
	if err != nil {
		log.Printf("Couldn't get role %v. Here's why: %v\n", roleName, err)
	} else {
		role = result.Role
	}
	return role, err
}

取得角色。

import { GetRoleCommand, IAMClient } from "@aws-sdk/client-iam";

const client = new IAMClient({});

/**
 *
 * @param {string} roleName
 */
export const getRole = (roleName) => {
  const command = new GetRoleCommand({
    RoleName: roleName,
  });

  return client.send(command);
};

$uuid = uniqid();
$service = new IAMService();

    public function getRole($roleName)
    {
        return $this->customWaiter(function () use ($roleName) {
            return $this->iamClient->getRole(['RoleName' => $roleName]);
        });
    }

範例 1：此範例會傳回 的詳細資訊lamda_exec_role。它包含可指定誰可以擔任此角色的信任政策文件。政策文件以 URL 編碼，並且可以使用 .NET UrlDecode方法解碼。在此範例中，原始政策在上傳至政策之前已移除所有空白。若要查看許可政策文件，以決定擔任該角色的人員可以做什麼，請將 Get-IAMRolePolicy用於內嵌政策，並將 Get-IAMPolicyVersion 用於連接的受管政策。

$results = Get-IamRole -RoleName lambda_exec_role

輸出：
